The Boeing Model 204 was an American biplane, pusher configuration flying-boat aircraft built by Boeing in 1929. Externally, the 204 looked identical to the Boeing Model 6E, but a number of internal changes, including increasing the passenger capacity to four, gave it a new type certificate and model number. [1]
Construction was started on five aircraft, but only two were completed. [1] The first, designated 204 and the second 204A. A third aircraft was built by a private owner who had bought the three incomplete machines. The 204A was a dual-control version which was later owned by Peter Barnes, who flew it on his private Seattle-Victoria, British Columbia main run. [2]
The C-204 Thunderbird, a modified 204, was the first type produced by Boeing Aircraft of Canada. These had altered wing and tailplane incidence and a reduction in upper wing area. The prototype was first flown on 30 March 1930, the first of a batch of four. They failed to sell readily, though they were sometimes leased for work. Eventually three were sold. All worked in British Columbia, remaining active until 1939. [3]

General characteristics
Performance
Boeing XB-55 was a proposed Boeing aircraft designed to be a strategic bomber. The XB-55 was intended to be a replacement for the Boeing B-47 Stratojet in United States Air Force (USAF) service.
The Northrop Alpha was an American single-engine, all-metal, seven-seat, low-wing monoplane fast mail/passenger transport aircraft used in the 1930s. Design work was done at the Avion Corporation, which in 1929, became the Northrop Aircraft Corporation based in Burbank, California.
The Boeing Model 15 was a United States single-seat open-cockpit biplane fighter aircraft of the 1920s, manufactured by the Boeing company. The Model 15 saw service with the United States Army Air Service and with the United States Navy as a carrier-based fighter.
The Boeing CC-137 was a transport and tanker aircraft which served with the Canadian Forces from 1970 to 1997. The Boeing 707-347C aircraft provided long range passenger transport for the military, VIP transport for government and air-to-air refueling for fighters such as the CF-116 Freedom Fighter and CF-18 Hornet. It was replaced by the Airbus CC-150 Polaris in the transport role and much later in the tanker role.
The Boeing 80 was an American airliner of the 1920s. A three-engined biplane, the Model 80 was built by the Boeing Airplane Company for Boeing's own airline, Boeing Air Transport, successfully carrying both airmail and passengers on scheduled services.
The Boeing B-1 was a small biplane flying boat designed by William Boeing shortly after World War I.
The Boeing Model 1, also known as the B & W Seaplane, was a United States single-engine biplane seaplane aircraft. It was the first Boeing product and carried the initials of its designers, William Boeing and Lt. Conrad Westervelt USN.
The Boeing Model 95 was a single engine biplane mailplane built by Boeing in the United States in the late 1920s to supplement the Boeing Model 40s being used on Boeing's airmail routes.
The Boeing TB was an American torpedo bomber biplane designed by the US Navy and built by Boeing in 1927.
The Boeing Model 7, a.k.a. Boeing BB-1 was an American biplane flying boat aircraft built by Boeing in the 1920s. The pilot and two passengers all sat in the cockpit, the passengers right behind the pilot.
The Boeing Model 8, a.k.a. BB-L6, was an American biplane aircraft designed by Boeing specifically for their test pilot, Herb Munter.
The Boeing L-15 Scout or YL-15 was a small, piston engine liaison aircraft built by Boeing in very small numbers after World War II. It was a short take-off and landing (STOL) aircraft powered by a 125 hp Lycoming engine. The L-15 was an attempt by Boeing to expand its product line as World War II drew to a close, and Boeing's production of combat aircraft declined. Boeing decided against marketing the L-15 as a general aviation aircraft, and the twelve that were produced went to the United States Army for testing, then were transferred to the United States Fish and Wildlife Service in Alaska for various duties.
The Boeing Model 203 was a three-seat biplane trainer build by Boeing in the late 1920s and used in the company training school.
The Boeing Model 64 was an American single engine biplane training aircraft built by Boeing in the 1920s that failed to gain any orders.
The Boeing Model 6D, a.k.a. Boeing Model 6E, Boeing B-1D and Boeing B-1E, was an American pusher biplane flying-boat built by Boeing between 1928 and 1929.
The Boeing Model 42 was an American biplane aircraft developed from the Airco DH.4, taking advantage of the large number of aircraft left over after the end of World War I.
The Boeing Model 81 was an American training aircraft built by Boeing in 1928. The Model 81 was a development of the Model 64. It was powered by a newly developed engine, the 125 hp Fairchild-Caminez 4-cylinder radial engine. Operating at a much lower rpm than most engines it required the use of a large high-pitch propeller.
The Boeing XPB was an American twin-engined biplane long-range patrol flying boat of the 1920s. A single example was built for the United States Navy.
The Boeing XP3B-1 was a proposed patrol aircraft, developed by Boeing for use by the United States Navy in the late 1940s. It was planned to be powered by two Allison T40 turboprops driving contra-rotating propellers, and utilized tandem landing gear. The project was cancelled before any aircraft were built.
The Travel Air Model 10 was a 4-seat single-engined light aircraft of the late 1920s. Twelve aircraft were built before production ended.
